Two Heads Are Better Than One: Knowledge Sharing in Organizational Social Networks

In this doctoral dissertation, the author explores three research areas of organizational network theory that relate to the analysis of organizational knowledge networks.

The third paper, entitled “Prerequisites of advice-seeking and knowledge sharing: Analysis of an organizational knowledge network,” explores the dynamics of advice-seeking in knowledge networks and their relational preconditions. Through a case study based on a survey and interviews at a Budapest-based management consultancy, it is found that (6) interpersonal trust and ...
